Teaching Guide to Shortcuts by Jeff Harris
Introduction
Shortcuts by Jeff Harris is a beautifully illustrated, fact-packed page that makes learning fun.
Each week, Shortcuts' multicultural cast (Juanita, K., Roland, Junior and James) offers facts,
riddles, jokes and puzzles to help kids learn about science, geography, animals, food, history and
holidays.
Each teaching guide provides ideas for expanding the lesson and creating discussion and learning
activities for your students. The grade level for the guides is usually 3rd to 4th, but they can be
adapted for use at other levels. The guides are broken down into four areas :
1. Questions for Discussion and Further Study
Designed to help students think and research, not just give one-word answers
2. Activity Ideas
Designed to allow students to be creative and teach themselves
3. Use the News
Designed to have students use the news in studying each topic
4. Quick Quiz
Designed to be adaptable to several grade levels, evaluate students' comprehension and build
vocabulary and math skills
You might use the teaching guides in the following ways:
Questions for Discussion and Further Study: Engage the entire class by asking each question
aloud and listing the students' answers on the board. Or have them use reference resources to
give their own answers to the questions. Allow them to discuss other students' answers after
they've researched the topics. Key words or phrases that can help students search for more
information are italicized.
Activity Ideas: Give the students a time limit to research their projects, using library or study
time. By having the students cite their resources you can check their work; or, alternatively, tell
them which resource(s) you prefer them to use.
Use the News: These can be worked on individually but we suggest they work in groups to learn
teamwork skills.
●
Quick Quiz: We suggest you review the quizzes ahead of time and change the phrasing
or difficulty level based on the students' abilities.

Subject Areas: The following information about aluminum will be discussed:
●
Identifying aluminum and steel
Is recycling worth it?
● Aluminum and other metals as alloys
Evaluation: Students may be evaluated using the following point scale:
●
Four points: Information is accurate, organized, shows creative thought/use of materials
Three points: Information is accurate and organized
Two points: Information is mostly accurate; organization needs some work
One point: Significant inaccuracies; lacks organization
Topics for Discussion and Further Study

Aluminum looks very much like steel. Is there a simple way to tell them apart?
Aluminum is the third most abundant element on earth. What are the first two?
Activity Ideas
●
Aluminum recycling is cost-effective, meaning it costs less to recycle aluminum than to
make aluminum from ore mined in the earth. However, the recycling process does
produce a lot of pollution. So there are some drawbacks to recycling. Read these two
articles about recycling and form your own opinion about the pros and cons of recycling
many different materials. Look for the main ideas in each paragraph of the articles
without worrying about the figures and details. This first article is about a 15-year-old in
India who recycles aluminum cans for a living:

This second article talks about the high costs of recycling most other materials:

Although aluminum is an element, it is usually combined with other metals to form an
“alloy.” What other alloys can you think of? Research and make a list of several alloys.
Include the name of the alloy and the metals that are combined.
Use the News
● Various metals are commonly used to produce things in our modern society. However,
plastic has become very popular also. Read the newspaper to search for things that have
metal, such as aluminum, in them. Could they have been made from plastic also? Which
things must be made out of metal? Why?
